Android Software Engineer

About the role

ActAI builds proactive mobile applications that bring AI into everyday communication, coordination and collaboration with minimal prompting. As an Android Software Engineer you own the Android client experience: how AI feels, behaves and performs on mobile. This is not a thin client role; you will build a production Android application where AI interactions are central.

Key responsibilities

• Build and maintain production Android apps using Kotlin
• Integrate AI-powered features (chat, vision, voice, recommendations) via backend APIs
• Design UX patterns for AI interactions, including streaming responses, retries and partial results
• Optimize performance, memory usage and responsiveness for AI-heavy flows
• Implement analytics, logging and feedback capture to support AI evaluation and iteration
• Collaborate with backend and ML engineers on API contracts and system behavior
• Ensure app stability, security and scalability in production

Required profile

• 3+ years of Android development experience using Kotlin
• Hands-on experience integrating AI features such as LLM, vision and speech APIs
• Experience with MLKit or light on-device inference
• Published production apps on the Google Play Store
• Comfort working in environments with latency, partial failure and non-deterministic behavior

Required skills

• Strong understanding of asynchronous programming (Coroutines, Flow)
• Familiarity with REST or gRPC APIs and structured data formats
• Strong debugging and performance profiling skills
• SQL / noSQL and TensorFlow Lite (on-device inference)

The interview process involves up to four virtual or onsite interviews, with a prompt decision once a fit is found.
